Title: Container with filling valve
Inventor: MURAKAMI TAKU
IPC: B65D30/24
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To eliminate need of heat-sealing operation after a powder or granular substance is filled and prevent a bag from breaking due to defective sealing by pinching and integrally heat-welding a tubelike filling valve comprising a high melting point resin film as an internal layer and a low melting point resin film as an external layer at a doubly overlapping portion of a container. SOLUTION: In a resin made film bag-like container 2 formed of two resin films overlapped and overlapped peripheries 2a, 2b, 2c, 2d which are heat-welded, a filling valve 1 formed of a tubelike laminate resin film having a high melting point resin film as an internal layer and a low melting point resin film as an external layer is pinched at arbitrary doubly overlapped portions to be heat- welded and integrally heat-welded. Heat welding is done at a temperature and in a pressurized condition so that the external layer of the valve 1 is heat- welded to the container but the internal layers are not heat-welded to each other. At the time of filling, the valve 1 is opened by deforming from the right and left, and a cylindrical filling device is inserted for filling an article. If the device is removed after filling, the opening restores to an original tightly attached state.

IPC: G03B27/32
Filed: 1985-08-26
Abstract: PURPOSE:To rapidly carry out an exposure and a development by using a black and white CRT having a higher light emitting luminance in a red color wave length area than in a blue color wave length area. CONSTITUTION:A black and white CRT using a fluorescent member obtained by mixing a fluorescent member P45 and a fluorescent member P22 in a ratio of 1:4 has a maximum peak value of about 620nm, the second peak value of about 710nm and a higher light emitting luminance in a red color wave length area and a lower light emitting luminance in a blue color wave length area. Accordingly, since in a color photographic paper 3, the light emitting luminance of the red color wave length area having low spectral sensitivity is made higher, a red color exposure time can be shortened to about one second. Since the light emitting luminance of the blue color wave length area having a considerably high sensitivity to the color photographic paper 3 is lowered, a blue color exposure time is substantially the same as the red color exposure time and a color balance is improved.
